Glider Interactions

An explosion occurs at t = 1.0 s between two gliders on a near-frictionless air track
which sends them
in opposite directions.

The interaction is shown in three ways: the animation, the graph (left
glider, right glider; co-ordinates can be determined from
a left-click of the cursor position (x,y) in yellow box:
time in seconds and position in centimetres), and the display
showing the current value of the graph for each glider.

Enter 0.4 kg as the mass of the left glider. Then choose either
Position or Acceleration to be plotted on the graph; the
animation will begin (almost) immediately. Press the control buttons to pause, step
forwards or backwards, to reset gliders, and to play again.

Questions:

Use the simulation to show that momentum is conserved before and after
they move.
